Which Oceans Border the United States?

The United States is bordered by two oceans:

• Atlantic Ocean – East Coast (Maine to Florida), Gulf of Mexico (Florida to Texas).
• Pacific Ocean – West Coast (Washington to California), Alaska, Hawaii.

The Indian Ocean does not border the United States. It lies entirely in the Eastern Hemisphere, bounded by Africa, Asia, Australia, and the Southern Ocean.

Note: The US also has coastlines on the Arctic Ocean (Alaska's North Slope) and the Gulf of Mexico (a marginal sea of the Atlantic). Some definitions include the Bering Sea (part of the Pacific) along Alaska's Aleutian Islands.
